To @Z22 whom it may concern:

.lle it' known that l, JOHN PLUMLEY liner LAM, ot l'l'liimingtoin-in vthe county of New Castle and State of Delaware, have invented `certain new and useliul Improvements in Electric r'ltep-llotions for Narpiiig-Machines, of which the following' is a specification.

This invention relates to electric stop-motions for warping-machines having the general characteristics of that described in Letters Patent to Lewis 1I. A'. Schwartz, No. l'lh'. dated. January S, 1889. This patented stop-motion is elnn'aetcrized by th'e einplovvnicnt. ot a visual annu neiator electrically actunteift, so that when a. break occurs in a yarn or end not only will the machine be stamped, out also the location of the particun lar' broken thread or end 'will be indicated. This a very important and desirable .teature, since there are prepared in a warping'- macninc frequently as many as two thousand three hundred threads or ends, and on t'hc occurrence of breaks much time has hithv erto been consumed in hunting,` for the broken threads---a difficulty whichis avoided bythe enniloyment ot the electric visual annun- .ciatoiz lh ere are several contingencies, how* "ever, ol' frequent occurrence that arcnot proovercome this diliieulty an electric alarn1-bell 1 is introdueel'l into the electric circuit, so that an alarm will be sounded when the machine stops, and thus the attention of the attendant will be attracted. It also frequently happens that the machine is stopped by a slack oceurrmg in one or more threads or ends instead of by breaks occurring.l llitlierto ithas been necessary to examine each thread of the group of threads indicated by the visual azinuueiat-or to see Whether it is breken or whether it is only slaclcencd. In accordance with the present invention ihcalarm-bell ci rcuit and the character el. the devices therein are such that' by turning the usual balancebeam to tighten the threads' the bell will cease ringing' in casethe machine has been stopped by a slack thread or threads; but it will continue ringing in ease a tllreadeis broken. Wuming-machines have also com monly been constructed so that when the, proper number of yards of Warp have been prepared a gong would be struck mechanically. In ease the attendant should be ont 0E hearing of the-gong, the, machine would continuet-o prepare Warp, and the additiolntl` amount would thus be wasted; or even in case ot` `the attendant hearing the gong a number et entra yards-will usually be prepared ecfore he can stop the machine.- In accordance with the present invention the machine is automatically stopped on the completion of: the proper amountol Warp, and the tact that the machine is thus stopped and not by the breaking or slacker-ning ot thread is indie cated by the' visual elect-ric annunciator.

A warping-machine provided with electric stop devices in accordance with the present invention will thus be automatically stopped on the breaking,` el athread @rend or ou the completion ofthe warp. 'llheparticula r threads or ends broken or the tact of the completion cl `the Warp will be inflicat/edQ on thc visual annunciator, and the stopping ot' the machine will be announced by an electric bell, which will contine ringing.;l until the attendant hasv done what is required.

The invention also includes improvements in the construction of the yarn-guide circuitu closing dropdlooks described in the Schwartz patent. It frequently happens with the dropllook's or the circuit-plates, with which they are adapted to make electric contact, that they become covered with lint to such an extent that electric contact is prevented; so the machine fails to stop when the threads break. The present invention includes an improved construction in this respect `for overcoming' this. dit'licultjv. e

The warping-machine is usually operated with a less number than its maximum n umber-cf threads or ends. Consequently when so used thennused circuits must be prevented tra Virene closine. The present invention incl udos meanaor rendering' inactive the 'unused cirL cuits.

rthc present improvements are illustrated in the accompai'lying' drawings, in which- Vie-*ire `l ia side view et so much of a ping-machine as nceeseary for an un- ,retarnling et' the preeent invention, show ric boil. lxige. i?, 3, 4, 5, ci.' vthe mechanical. stop and einer mechanical features. diagram showing the electrical eonmain drive-shaft el the warping i farryiinr tant and loose jil'inlleys n. nl', the lnilance-heam eund which the ,l fis, Seid balance-beam having the maal hand balanceo el h.

C is one et the creca` et the machine, having anumbe'r et Sections ilicd with spools c, on which the yarn or thread is wound. There are as many creeis and an many see- 'tione and specie ineach ereel as the character ci' the 'Work demande; but only one creci is ill nstrated. Usually there are six creeis and seven sections in each creci.

The motion of the machine is stopped by means ci a shipperiorlc D, which carries the drive-belt from the i'ast to the loose pulley on the drive-shaft A. This shipper-'fork may be moved by any convenientmechanism, thel action of which is initiated by the movement of the armature ot' an electro-magnet, auch mecha-unime being well known. l prefer the mechanism illustrated, which, howevei-,is not new with me, and constitutes iu itself no part et' my inver "a Geac-ting with 4the shipper-fork is a s retiring-actuated shitting-rod E, w` ih united in the framc Work of the m wie slidclongitud inally. The .k e Le moved to shift the belt from the nel rycte the loose pulley a (thus etoppn vvle machine) by a coiled Spring` il. AWhen the machine is running, the rod E is held retracted, and the spring (Z is held. under reunion h lxmeanset a catch-lever c, one end of which engage-,s1 a notchf on the 'slii'ling shitting-rod. Tothe other end of this level pivoicd a. balanced lever y, which lies in :substantially horizontal plane. lirom one end oi 'this lever g is suspended by a rod il the armature of an electro-magnet l. Thelever o is balanced so that iiiormally the arma ture i' is held upliited above the magnet. when, however, the electro-magnet vis onergized by the passagethrough or around it of Ian electric current7 thcarmature is easily drawn down, there bcingbut little weight to be overcome. (in the other armfrom that to which is pivoted the armature-rod connection the lever g carries an upwardly-projecting `catch it. l

On the main drive-shaft A. is a cani er eccentric l, against which refaisH one end ofl a spring-heid lever m. lever ia connected by a link with a rcciprocat vpied bythe catch on lever g.

The upper end otthisin g' bar n, hold in suitable `froides. The motion communicated by the cam to the lever m is in turn communicated by thc lever to the bar n, which thus constantly reciproeatcd while the machine is running. The reciprocating bar u has a proj cctinl stud o, which reciprocate's just above the position normallyoccn- W hen the magnet F is energized, its armature is depreseed and the catch 1.1 is lifted into the' path et' the stud o, so that the lever g is swung on its pivot. by the movementoi. the bar n. 'ily this movement the lower end ot the lever e is released from thc-notch f in thcsliding shifting-rod l1), which is then free to. be actuated by its spring and no stop the machine. iience it is evident that the passage of an electric current through the magnet F will stop the machine. v

ihe usual mechanism i'or sounding a gong to give notice that the warp is completed is only partially shown. This mechanism includes a gone; p, which is adapted to be struck by a lever i] at the proper time. This lever is actuated by a train ot' gearing of wellmown construction, which is not shown, be cause it is well known and because it constitutes no part ot' the present invention. A mechanism of: the character referred to is, for example, shown and described in Letters latent to J. l. and (l. Ashworth, No. 183,619. dated October 24,1876. The only portionsot this mechanism i'or indicating' the completion ot' the warp that are essential to the present. invention are'the gong and the strikinglcver, and itis only necessary to know that the lever is adapt-ed to be moved at the completion of the warp.

i the electric visual annunoiator, which is (or may be) ol? well-known construction. l prefer to employ an annuneiator made in ac corda-nce with Letters Patent to Aaron D. l3lod fetty No. fifhdzh4 dated Marcil S, i857. This annunciator has a series of sight-targets fr fr, which are exposed to View on the excitation oi their respective magnets '.ss. 'lhe number ci. the targets depends upon the number of creeis and sections. Preferably there is a target lfor each creol-section, so that a machine havii'ig forty-two sections would have forty-two targets Ain its annunciaior. 'lherc may be a separate target ior indicating the completion ci the warp, or one ofthe other targets may be selected for this purpose. Since only one creel is illustrated, having IOO llO

seven sections, the 'annuncialor shown has eight targets, including a separate target for indica-ting thatthe warp is completed.

of the dynamo. Each separate wire 2 lecon-- nocted by a wire G, with one of'th'e magnets s' of the visual aunnnciator, and all of the magnets of the visual annunciator are'connected with a retu'rnwvire 7,leading to the negative pole of the dynamo. This circuit 'formed hy the wires 1,2, 3, a, 5, G,and 7,-con Stituting the main-line connections, does not pass through the electric bell. lt has heen found that the stop-magnet F, the bell-niagnet, and the annunciatoranagnets are all located in the Same circuit 'the amount of energy furnished by a small dynamo, such as can conveniently he run by attachment to themot'orof the machine 'without an increase of "power, will heinsuilicient to actuate them all simultaneously, especially so in case a number of the threads in diiierent sections should break simultaneously, as frequently a happens. llendo the bell-magnet is located in a shunt-line connecting; withthe main-line conneetions, `so as to exclude the stop-magnet. ,Between the dynamo and the stop-magnet F a brauch wire S leads from wire 2lto the hell IH. From the bell .ll a wire Sl leads to a normally-closed hell-switch Q, by means ot which the bell-circuit can loe cut out, if desired, to slop the bells ringing', and Yfrom the switch a wire leads to the wire il, and thence by Wires l n, drop-hooks Lwires uf .2 d, annunciator, and i'etur11-\vire 7 to the dynamo. rl`l1e wires S, .9,and l() thus constitute a shui-inline, which connects With the main line and e.\:- cludes the stop magnet F. ln order that when a hooi; drops the current will not be shunted through the bell-circuit, and so fail to act-nate the slop-magnet, a resistance-coil coily It shall be greater than that of the stop magnet. Assume, now, that the machine is running` and one of the threads lneake. lts hook' I immediately drops, closing the stopniagnet circuit and so stopping' the machine by the release of the Spring-actuated sliding' shifting-redit). The movement of-this rod E in stopping` the machine, however, breaks the contact between the spring C) and the plate P on the shifting-rml, thus lneaking the main or stop-magnet circuit. 'lhe rcsistanccof the Stop-magnet no longer being; encountered, the electric eurrenttheu traverses the shunt or bell line and sounds the bell. Thebell contin ues' to sound. until theattendr-Lnt does what is necessary.' Practice has, however, shown that even with the stop-magnet out of the circuit the ai'lnnnciator will not indicate all flei'ective threads when several happen to he broken or run out nimultaueeusly. llonce to insure the imlication of all defective threads inea-us are provided for cutting* ont the hellmaguet and so turning the full force olA- the dynamo into the annunciator#magnet To th'isend a wire 'll branches from the wire S, being connected therewith between the resist ance-coil and the dynamo. 1Wire 'll leads to anormally-oiien aiuiuneiator-switch S. From the switch S a wire l2 connects with the wire l0, and thence through 5, l, i', I, u, 2, G, an nunciator to the dynamo. Yilhcn therefore the machine stops and the hell rings, the attendant steps to the switch S and closes the same, thus cutting;l out the hell, causing it to stop ringing', and concentrating; the current upon the aununeiator. 'lhus all the annuncialo'r-magucts in circuit are excii ed and their targets exposed. lIn practice it has been louud that ordinarily none of the annuneiatormag nets will act until the switch B is closed, the electric energy hein too far exlul-usted hy the stop and l ellma.mci's to excite any ot the auf nunciator-inagnets sinnilianeousl y. The attendant then repairs the indicated threads and starts the machine. l1, frequently hap pens, however, that ihe-machiue is stopped hy slack threads aud'not hy the occurrence of breaks, so that the attention. o'l the attendant to the creeis is unnecessary. The introduction of the hell-circuit secures the important advantage ot' enabling the attendant to ascertain whether the machine has heen stopped by slack threads or otherwise, and it stopped hy several threads, partly slack and partly broken, it enables only the broken threads to he indicated on the annuuciator. Thusv much time is saved. 4When the attend* ant hears the hell ringing, his iirst act is to turn the imflancc-heam .ll in the proper di rcction to tighten the threads. ll then ther machine has heen stopped hy slack threads alone, their respective hooks l will he liltcd,y thus ,breaking the circuits closed by them, andthe bell will instantly cease ringing, thus showing that there are no broken threads. lf, however, the hell still continues to ring, there are one or more broken threads. Accordingly the annunciator-switeh is then closed and only the tari; its are exposed which indi cate the location of the broken threads.

lu order to stop the machine when the warp is completed, advantage is taken of the usual mechanism for this purpose, hari ng' the met al lever (l, which strikes the metal gong` p. This vis substantially the same movement as that cllected bythe drop-hooks I, and consequently the lever q may he electrically connected as though it were one of the hooks l and as though its gong; 7l were one of the wires or rods n'. A branch wire lil leads from wirc to the lever q, and a wire lil leads from the :rongj to a normally-closed switch T. 'From the switch 'l a wire l leads either directly to a separate aununeiaitor-maguet s, as shown, or to' any selected one ol the wires (5. llence when the warp is completed the same effects are produced as when one of the drop-hooks I acts.

'lhe object oi the stopswiteh 'l is to break" the warp-completion circuit while thc machine is being made ready for the preparation of a new warp. The addition of these stoppin devices enables an attendant of average intelligence to do as much. work in a given time with one warpiiig-machine as two attendants will do with two ordinary warping;-y
